L.S. When instructing VBoxManage to boot into a specific partition, using the -mbr option with an appropriate mbr file, that appears not to work as expected.
My host is a linux system and the raw VM has Windows7. When launching the VM I get a black screen that displays the static text "GRUB _" in the upper left corner. This indicates that somehow GRUB is accessed where it ought be bypassed. Maybe the physical mbr is still used instead of the replacement mbr. When manually overwriting the first 512 bytes of the resulting *-pt.vmdk file with the contents of the replacement mbr file, the vmdk file does do what's expected. My system: VirtualBox 4.3.6 r91406 Host: openSuSE Linux 13.1 (kernel 3.11.6-4-desktop) 64bit Guest: Windows7 64bit (Before using Virtualbox 4.3.6, I was using 4.2.18 on openSuSE 11.4, with which I didn't experience this problem.) Note aside: The observed behaviour occurred regardless whether GRUB2 or the legacy GRUB boot loader was used for the physical host machine. I write this because several discussion threads, that can be found on internet, mention the same symptom in the converse combination: launching a raw linux VM from a Windows host. In these discussion threads, GRUB2 is indicated as the culprit.
